Whether parental authority and custody over the child should be awarded to the father instead of the mother
Extracted holding
The mother remained the more suitable custodial parent in the child's best interests.
Extracted reasoning
The cantonal court did not violate federal law by relying on the child's best interests, equal parenting capacities, the stability of the existing arrangement, the father's instrumentalization of the child, and the mother's greater ability to preserve stable relations.
